Chisa Izumi and Jin Satsuki are a devoted couple navigating the familiar rhythms of high school romance, but their trust is shaken when Chisa’s friend, betrayed by her own partner, warns her that no man can be truly faithful—including Jin. This central conflict unfolds in a collection of interrelated short stories, each penned by a different creator, that together form a single-volume anthology. The setting is the everyday world of Japanese high school life, with classrooms, after-school meetups, and quiet corners where uniforms are shed and hidden feelings surface. Other stories in the volume explore similar tensions: a student council president’s secret affair, a dangerous game of temptation between classmates, a bittersweet teatime encounter under moonlight, and a moment of fleeting intimacy that changes everything. Each narrative arc centers on the moment of vulnerability that comes when the school day ends and characters step out of their prescribed roles, confronting desire, jealousy, and the gap between public faces and private truths. The anthology weaves these perspectives together into a single portrait of adolescent love in all its messy, earnest uncertainty.
